WINDOW-CLEANER.

ToaZZ whom it may concern:

TER, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Window- Cleaners; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

The objectof my invention is to'provide meansfor clearing window-glass of deposited vapor, moisture or ice, so that vision through the glass is unobstructed, said means comprising a pair of pivoted scrapers and wipers arranged to contact with both surfaces of the glass, and be actuated by hand to clear the sameas occasion may require.

a p The invention therefore consists in certain pecullarities of construction and combination of parts as hereinafter fully set'forth with reference to the accompanying draw-- ings and subsequently claimed.

In the drawmgs: Figure 1 represents a front View of a scraping and wiplng means embodying the features of my invention, an

arm of same being shown attached to a fragment ofglass with parts broken away and parts in section, as'indicated by line 11 of Fig. 2; Fig. 2, a longitudinal section of the same, as indicated by line 22 of Fig. 1;'

Fi 3, an endview with the glass in section, as indicated by line 33 of Fig. 1; Fig. 4;, a detail inverted plan view of a portion of one of the scraper-arms and washer into which the same is countersunk, and Fig. 5, a crosssection of the arms on line 5 5 of Fig. 2.

Referring by letter to the drawings, A in- 1 dicates a plate of transparent glass for a the car, locomotive-window, or the like, the same bein bored to receive a cylindrical post B, which extends from and forms part: (1 cap or washer .C,'having a of an enlar conical head a as shown. The washer is counterbored concentric with its 0st to receive' a gland D ofa metal disk preferably of greater diameter than the washer, and inter osed, between" the disk and glass is a gas at F of soft material, preferabl rubber.-

The cy indrical 0st B projects through the glass, and has tted thereon, adjacent'to lass surface, another gasket F' over whic is placed a disk E havinga gland D, said disk being similar to the one previously described. At the point where the post B comes. flush with the gland of the last Specification of Letters Patent.- Application filed November 19, 1906.

' to receive a blind conical nut H,

, which is Serial No. 344,008.

receive'the squared shank of the aftfiesaid post.

A screw-threadedextension G of the post projects beyond the face of the washer C, that serves to .bind the several parts together and form a tightly clamped pivot-joint, that is so cushioned against the faces of the glass as to render breakage thereof, through variation of temperature, virtually impossible.

Owing to the shoulder-post the draw or clamping strain upon the glass is regulated by the thickness or yield of the gaskets, whlch thlekness may e varied in order to get a uniform clamping strain when a glass of different thickness than that shown is used.

. named disk, said post is'formed'with a re- Be it known that I, EDWARD J. SCHOWAL- J Scraping-arms I, I, are detachably fitted between thewashereind disk members of the joint, the construction -of the arms being as follows :The shank-portion of each arm consists of a flat plate having forked extensions J, which are adapted to enter corresponding recesses formed by the disks and countersunk channels K, K, of the Washers,-

the channels being of depth equal to the thickness of the forks, and connected by a cross-cut to form shoulders against which the base of the forked end of the shank abuts. From the shanks the arms are pressed or otherwise formed into grooved fingers having flared scraping-edges L, which edges center groove being dove-tailed to receive a similarly dove-tailed-wiper strip L, which; has rubbing-contact with the glass at its lower edge, said'strip bein of any suitable material, eitherrubber or a sorbing.

saidarm is fitted, there being ahandle' N projecting from one of the aforesaid arms for the purpose of rotating the same, it being understood that the handle is upon the armon that side of the glassadjacent the operator.

By the above described apparatus it will contact with the surface of the glass, the 1 bejseen that whenthe glass becomes blurred from atmospheric condit1ons,- the operator Normally the springs M lie close alongthe arms, but when the shanks of these arms are engaged with the pivot-joint in connection with the glass, the free ends of said springs are lifted and allowed to snap into place on the conical head a of. one of the washers and the conical end a of the nut H respectively, said springs being then under tension to not only lock said arms in said joint but also to exert a pressure by which the aforesaid arms are held tight against the faces of said glass so as to produce the most efiicient results, when operated toscrape ice or sleet from the same.

If the apparatus is not in use, or should the arms be in the way,'when it is desired to raise or lower the .windowto which they are attached, said arms may be readily dissorted in the arms; depending u on the cliengaged from the joint.

By the provision for attaching strips, the latter when worn" ma replaced, or different grades 0 the wiperreadily be wipers inmate or conditions to be conte ed with.

whic

The invention herein particularly set forth is particularly applicable to the pilot windows of motor cars, locomotives, marine vessels and automobiles.

I claim:

1, A window-glass cleaner comprising a pair of channeled washers, a post that extends from one of the washers through an aperture in the glass and engages the other 0 said washers, gaskets opposing the sides of said glass, disks interposed between thegaskets and washers, and glass cleaning arms having shanks in detachable enga ement,

with the washer-channels against sai disks. 2. A window-glass cleaner comprising a pair of channeled washers, a post that extends from one of the washers through an I aperture in the glass and engages the other of said washers, gaskets opposing the sides of the glass, disks inter osed between the gaskets and Washers, g ass-cleaning arms having shanks in detachable engagement with the washer-channels against said disks, and springs in connection with said arms for locking engagement with the aforesaid washers.

In testimony that I claim the foregoing I have hereunto set my hand at Racine in the county of Racine and State of Wisconsin in the presence of two witnesses.
